# Intlayer Preact Usage
## Core Philosophy
Intlayer promotes **Component-Level Content Declaration**. Instead of a massive global translation file, content is declared in `*.content.ts` files adjacent to the Preact components that use them.
## Workflow
To create a translated component, you need two files:
1. **Declaration:** A content file (e.g., `myComponent.content.ts`) defining the dictionary.
2. **Implementation:** A Preact component (e.g., `MyComponent.tsx`) using the `useIntlayer` hook.
### Declare Content
Create a content file using `t()` for translations.
**File:** `src/components/MyComponent/myComponent.content.ts`
```typescript
import { t, type Dictionary } from "intlayer";
const content = {
// The 'key' must be unique and matches what you pass to useIntlayer()
key: "my-component",
content: {
text: t({
en: "Welcome",
fr: "Bienvenue",
es: "Hola",
}),
},
} satisfies Dictionary;
export default content;
```
## Setup
- [Vite and Preact](https://intlayer.org/doc/environment/vite-and-preact.md)
## useIntlayer Hook
```tsx
import { useIntlayer } from "preact-intlayer";
const MyComponent = () => {
const content = useIntlayer("my-component");
return (
<div>
<h1>
{/* Return content */}
{content.text}
</h1>
{/* Return string (.value) */}
<img src={content.text.value} alt={content.text.value} />
</div>
);
};
```
